New build mastic in Larbert, done properly
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation. We work on windows & doors, skirting & floors and show homes, and the jobs we see most are frame joints opening as the plaster dries and joints pulling apart as timber shrinks.
Work in a place like Larbert is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
We stand behind the work with a one-year guarantee.

Honest limits
In fairness, some problems need a different trade:
- Your warranty claim itself, which is between you and the builder
- Cracking that points to a structural problem
- Leaks from pipes, valves or wastes, which need a plumber

Advice
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a place like Larbert, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.
Can new sealant go on top of the old bead?
No. The old sealant is cut out fully, then clean and prime the joint, before resealing.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, while small cosmetic gaps can wait a while.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Surface by surface
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
